[W]hen we refer to all Kurdish fighters synonymously, we simply blur the fact that they have very different politics. . . right now, yes, the people are facing the Islamic State threat, so it’s very important to have a unified focus. But the truth is, ideologically and politically these are very, very different systems. Actually almost opposite to each other. —Dilar Dirik, “Rojava vs. the World,” February 2015

When your relatives die, there’s usually a place you can go to pay your respects, like a cemetery with a grave where you can lay a stone and talk to them. The only place I have is Auschwitz and going back there for the first time will be the first and last chance I have to be able to return to the people I loved who I lost there and in other concentration camps.

Information about Auschwitz became available to the Allies as a result of reports by Captain Witold Pilecki of the Polish Home Army (Armia Krajowa), who volunteered to be imprisoned there in 1940. As "Thomasz Serfiński", he allowed himself to be arrested in Warsaw and spent 945 days in the camp, from 22 September 1940[200] until his escape on 27 April 1943. Michael Fleming writes that Pilecki was instructed to sustain morale, organize food, clothing and resistance, prepare to take over the camp if possible, and smuggle information out to the Polish military.[201] Pilecki called his resistance movement Związek Organizacji Wojskowej (ZOW, "Union of Military Organization").[200]

Los recintos, las alambradas, las torretas de vigilancia, las casamatas, las horcas, las cámaras de gas y los hornos crematorios de este campo de concentración y exterminio, que fue el más vasto de los creados por el Tercer Reich, dan fe de las condiciones en que se perpetró el genocidio nazi. Según los trabajos de investigación histórica, entre 1.100.000 y 1.500.000 prisioneros –en gran parte judíos– fueron sistemáticamente privados de alimentación, torturados y asesinados en este campo, símbolo de la crueldad ejercida por el hombre contra sus semejantes en el siglo XX.

In Autumn 1943, the camp administration was reorganized following a corruption scandal. By the end of 1943, the prisoner population of Auschwitz main camp, Birkenau, Monowitz and other sub-camps was over 80,000: 18,437 in the main camp, 49,114 in Birkenau, and 13,288 at Monowitz where I G Farben had its synthetic rubber plant. Up to 50,000 prisoners were scattered around 51 sub-camps such as Rajsko, an experimental agricultural station, and Gleiwitz, a coal mine (see The List of the Camps for a complete list of those sub-camps).
While top officials reported to Hitler and followed his policies, they had considerable autonomy.[194] He expected officials to "work towards the Führer" – to take the initiative in promoting policies and actions in line with party goals and Hitler's wishes, without his involvement in day-to-day decision-making.[195] The government was a disorganised collection of factions led by the party elite, who struggled to amass power and gain the Führer's favour.[196] Hitler's leadership style was to give contradictory orders to his subordinates and to place them in positions where their duties and responsibilities overlapped.[197] In this way he fostered distrust, competition, and infighting among his subordinates to consolidate and maximise his own power.[198]
The victories of Operation Barbarossa in the summer and fall of 1941 against Hitler's new enemy, the Soviet Union, led to dramatic changes in Nazi anti-Jewish ideology and the profile of prisoners brought to Auschwitz.[37] Construction on Auschwitz II-Birkenau began in October 1941 to ease congestion at the main camp. Reichsführer-SS Heinrich Himmler, head of the Schutzstaffel (SS), intended the camp to house 50,000 prisoners of war, who would be interned as forced laborers. Plans called for the expansion of the camp first to house 150,000 and eventually as many as 200,000 inmates.[38] An initial contingent of 10,000 Soviet prisoners of war arrived at Auschwitz I in October 1941, but by March 1942 only 945 were still alive, and these were transferred to Birkenau, where most of them died from disease or starvation by May.[39] By this time the Nazis had decided to annihilate the Jewish people,[40] so Birkenau became a labor and extermination camp.[39][41]
Around 7,000 SS personnel were posted to Auschwitz during the war.[84] Of these, 4 percent of SS personnel were officers and 26 percent were non-commissioned officers, while the remainder were rank-and-file members.[85] Camp guards were members of the SS-Totenkopfverbände (Death's Head Units).[86] Approximately three in four SS personnel worked in security. Others worked in the medical or political departments, in the camp headquarters, or in the economic administration, which was responsible for the property of dead prisoners.[85] SS personnel at the camp included 200 women, who worked as guards, nurses, or messengers.[80] About 120 SS personnel were assigned to the gas chambers and lived on site at the crematoria.[87]
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte).[11] Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.[12]
